The emx3 is The laTesT developmenT

in sofT sTarTers providing a

compleTe moTor sTarTing and

managemenT sysTem.

WiTh an impressive range of

feaTures in a single user friendly

package, never before has moTor

conTrol been so simple.

MOre COntrOl

Not only does the EMX3 soft starter

feature Constant Current and Current

Ramp, but the EMX3 is the world’s first

soft starter to control acceleration. We

call it Adaptive Acceleration control.

According to your application require-

ments you can now select between early,

constant or late acceleration/decelera-

tion. This level of choice is only available

from AuCom.

More control means smarter starts and

smoother stops that reduce downtime

and eliminate water hammer problems.

eAsy tO Use

The EMX3 is easy to use during installation,

commissioning, operation and even trouble

shooting.

Quick setup gets your machinery running

in next to no time, informative screens

advise your operator on the performance

of your motor and real language trip

messages pinpoint exactly where any

issues lie.

Options for control wiring from the

top, bottom or left side provide greater

flexibility, plus unique wiring looms and

cable retainers make for a faster, tidier

install. You’ll soon experience how easy

the EMX3 is to use.

feAtUre set

The EMX3 is a smart, dependable and

easy to use soft starter. New design

features make the EMX3 the perfect

solution for quick set-up or more

customised control, including:

• Large LCD screen with multi-language feedback

• Remote mountable keypad station

• Intuitive programming

• Advanced start and stop control functions

• A complete range of motor protection features

• Extensive performance monitoring and event logging

Xlr-8: AdAptIVe ACCelerAtIOn COntrOl

AuCom’s new EMX3 soft starter

introduces a new generation in soft start

technology: XLR-8 Adaptive Acceleration

Control. XLR-8 gives you an unprecedented

level of control over your motor’s

acceleration and deceleration profiles.

Using XLR-8, the soft starter learns your

motor’s performance during start and

stop, then adjusts control to optimise

performance. Simply select the profile

that best matches your load type and

the soft starter automatically ensures the

smoothest possible acceleration for your

load.

Contact your local distributor to see an

EMX3 demonstration today.

reAl lAnGUAGe In reAl tIMe

AuCom wants to make your job easy, so

the EMX3 gives real-language feedback

messages, so you don’t have to look up

codes to know what’s happening. With

real-time metering displays and a 99-

place event log recording time-stamped

details of operation and performance, it

has never been easier to track how your

motor is behaving.

GrApHICAl dIsplAy

In many cases we’ve done away with

language altogether, using real-time graphs

of motor operating performance and

current to quickly and clearly illustrate

exactly how your motor is performing.

reMOte dIsplAy MOUntInG

The keypad is easily mounted on the

exterior of your enclosure, using an

optional keypad mounting kit. When

mounting multiple soft starters in a

single enclosure, this allows centralised

control from a single location, with all the

relevant information. Mount a number

of displays next to each other for quick

diagnosis of problems. (IP65 when

mounted).

sMArter stArtInG

The EMX3 puts you in control of motor

starting. Depending on your application

requirements you can select the best soft

start control method.

For applications requiring precise control

of motor start current the EMX3 offers

a choice of Constant Current or Current

Ramp start modes. For superior control

over acceleration or deceleration choose

XLR-8 Adaptive Acceleration Control.

sMOOtHer stOppInG

XLR-8 also provides precise control over

soft stopping and is ideal for applications

requiring a smoother soft stop. XLR-8 is

ideal for low inertia loads such as pumps

and conveyors, and can substantially reduce

or eliminate the effects of water hammer.

BrAKInG

For high inertia loads, the EMX3

incorporates AuCom’s latest braking

algorithm, letting you take precise

control over the motor’s stopping time.

Shorter stopping times help improve

your production efficiency by reducing

downtime between operating cycles.

AdVAnCed OperAtIOn

To meet the unique requirements of your

application, the EMX3 offers a range of

advanced features. The EMX3 meets the

needs of specific applications including:

•Pumping(e.g.highheadapplications)

• Compressors(optimisingloadcontrol)

• Bandsaws(easybladealignment)

• Irrigators(built-intimer).

sIMUlAtIOns

Need to test the installation before

connecting a motor? The EMX3

simulation functions let you test the soft

starter’s operation, external control

circuits and associated equipment

without connecting the soft starter to

line voltage or a motor. The EMX3 has

three simulation modes:

• run simulation: simulates a motor starting, running and stopping to ensure correct installation.

• protection simulation: simulates activation of each protection mechanism to confirm correct protection response.

• signalling simulation: simulates output signalling.

easy To insTall, easy To operaTe

eAsIer InstAllAtIOn

If space is at a premium in your motor

control centre, the EMX3’s compact size

will save you space and trouble. Internal

bypass contactors, built-in monitoring and

indicators, and extensive on-board input

and output functionality reduce the need

for space and cost of external equipment,

as well as simplifying installation.

reMOVABle COnneCtOrs & UnIQUe WIrInG lOOM

Installation is easy with plug-in control

terminal blocks. Simply unplug each

block, complete the wiring and re-insert

the block.

Using the EMX3’s unique and flexible

cable ways, cables can be efficiently

organised for wiring from either the top,

left or from below.

fAster COMMIssIOnInG

The EMX3 has been designed for ease of

use, and the user-friendly menu is no

exception. After a tidy installation, a

quick setup guide helps you configure

the starter for common applications by

suggesting a typical setting, which you

can then fine tune to suit your needs, all

accessible from the easy to use keypad.
